Abstract

Spin-coated gold colloids showed a time-dependent increase in emission upon illumination at 532 nm. The emission originated from point-like locations and displayed blinking. The emission spectra of the individual spots and their spatial location remained constant, which is distinct from recent reports on silver nanoparticles. These results suggest the use of emission from gold clusters in nanophotonics devices and as luminescent probes with potential applications in medical imaging.

摘要

旋涂金胶体在532nm光照下发射随时间增加。发射源自点状位置并呈现闪烁。各个斑点的发射光谱及其空间位置保持不变,这与最近关于银纳米颗粒的报道不同。这些结果表明金簇发射可用于纳米光子学器件,并作为具有医学成像潜在应用的发光探针。
